The U.S. Environmental Protection Agency (EPA) announced on February 23, 2023, that the New Chemicals Program will hold a webinar on February 28, 2023, on EPA’s process for assessing the potential risks of new chemicals under Section 5 of the Toxic Substances Control Act (TSCA) and the types of data EPA considers in this assessment. EPA states that specifically, the upcoming webinar will cover commonly missed information in Section 5 submissions and how EPA evaluates environmental release information for operations that occur at non-submitter sites. Registration is now open. 

As reported in our June 27, 2022, memorandum, in June 2022, EPA announced outreach to describe how it evaluates engineering (i.e., environmental release and worker exposure) data for new chemical submissions and common causes of EPA having to reconduct risk assessments (i.e., “rework”). The goal of this effort is to prevent delays of EPA’s new chemical reviews caused by rework.

The February 28, 2023, webinar is the third and final webinar in a series to increase the efficiency and transparency of EPA’s new chemical determinations. The first two webinars, held in July and October 2022, focused on common issues that cause EPA to rework risk assessments, clarifications of common misconceptions in EPA’s new chemical assessments, and other information related to TSCA Section 5 submissions. More information on these webinars is available on EPA’s website and in our July 28, 2022, and October 25, 2022, memoranda.
